Windows XP Operating System Power Management States
The Advanced Configuration and Power Interface (ACPI) uses different levels or states of
power management. These power management states occur automatically, based on the
notebook's default settings, or manually, when invoked.
®
The Windows XP operating system ACPI power management states include:
• Monitor timeout
• Standby - also known as Save-to-RAM (STR), Standby manages power by saving your
current working environment to memory and shutting down most system devices.
• Hibernation - also known as Save-To-Disk, or Save-To-File (STF), Hibernation manages
power by saving the current working environment to an area on your hard disk before
turning off your notebook. When you restart the notebook, any programs and documents
that were open when you turned the notebook off are restored on the Desktop.
